One-Person Birthday Party

It's my party, and I'll cry if I want to.

Pinkie Pie: Thank you all so much for coming! It means so much to Gummy.
Pinkie Pie voicing a bucket of turnips: Could I have some more punch?
Pinkie Pie: Well, of course you can have some more punch, Mr. Turnip. (twitches)
Pinkie Pie voicing a pile of rocks: This is one great pahty! You really outdone yourself!

— My Little Pony: Friendship Is Magic, "Party of One"

You've spent hours hanging balloons, decorations, and banners on the wall. You've cooked the food to perfection. The cake is ready, and the candles have already been lit. The presents are waiting to be opened. You even have the music all sorted out. It's a perfect birthday party.

There's just one problem: nobody else is coming.

Birthdays are supposed to be a great occasion to get together with friends, when everything is about you. So when someone has only themselves with whom to celebrate their birthday, it's a sign that they really are alone.

Writers tend to use this trope to establish that the character in question is The Woobie (if Played for Drama) or The Chew Toy (if Played for Laughs). This character may also be a Cloud Cuckoo Lander since these will often misunderstand the point of rituals, and may make a Literal-Minded interpretation of the "everything is about you" idea. (If a friend is there, then not everything is, technically, about you.)

Compare Not-So-Forgotten Birthday and A Birthday, Not a Break. Could be the result of a Perennially Overshadowed Birthday or Birthday Buddies situation, with everyone choosing to celebrate the holiday or the other person's birthday instead.

At least this character is making an effort. Contrast Never Had a Birthday Party, where a character does not bother with the pretense of a celebration, maybe because they do not even understand the idea.

Has absolutely nothing to do with Two-Person Pool Party.

Unfortunately, this is only the start of his troubles, as the booth next to him is a Scarecrow henchmen about to deploy fear gas in the diner.
• The "Claptrap's Birthday Bash" sidequest from Borderlands 2, where you send invitations to Claptrap's birthday party for him. None of the guests accept the invitation, so you end up alone with Claptrap. You could make it a little less sad by having four players go, but that's four out of six playable characters — under the best circumstances, not even all the Vault Hunters go to Claptrap's party, which only ends up lasting a few minutes. Word of God states that the mission was based off of an actual One Man Birthday Party that the creative designer once witnessed.
• An unusual variation in Freebird Games' standalone title Do You Remember My Lullaby?.

She decides to surprise him with it and surreptitiously begins skipping meals in order to save up enough money for the ingredients. However, on the day of her son's birthday, he goes on a scheduled visit to his (much richer) father's home, who invites him to stay overnight.

• In the Ruin DLC for Five Nights at Freddy's: Security Breach, this is implied. The last of Roxy's recollection lines to Cassie is "Did you book your party? I'm sure your friends will show up this time." Roxy is honestly trying to reassure Cassie about this, implying that when Cassie had her birthday party at the Pizzaplex, Roxy was the only other one there. This is done to highlight the tragedy of the scene. Cassie has to deactivate Roxy to advance, which the game treats as a Mercy Kill that Cassie still feels terrible about doing, since Roxy was the only person who ever cared at Cassie's birthday party.
• In NieR Re[in]carnation, the "Garden of Benediction" event is about the Girl having one of these. Since she's grown up in absolute poverty, she has no idea what a birthday cake looks smells, or tastes like, so she makes one out of dirt.

• A disturbingly large amount of fanwork depicts Alice Margatroid of Touhou Project this way, perhaps due to her (fanon) isolationist, tsundere persona. Yuuka Kazami occasionally gets this treatment◊ too, though in her case it's because of her (sometimes supposed) Ax-Crazy personality.

Web Animation

• Variants in Episode 39 of The Most Popular Girls in School: Brittnay, Mackenzie, and Trisha throw a New Year Eve's party, but nobody (except Deandra, eventually) shows up; kind of Justified, as they're Alpha Bitches. OTOH, this is deliberately Invoked with Rachel's & Judith's party.

• The Taco-Man Paint short "Today is My Birthday" has the title character throw one for himself, because all his friends died beforehand.
• In the Ultra Fast Pony episode "Purple Party Pooper", Twilight sends invitations for her birthday party, then finds out that no one is planning to attend. She becomes increasingly unhinged as she tries to figure out why her friends won't come.

Webcomics

• In Brawl in the Family, one of the Waluigi-themed comics depicts Waluigi as the only attendee of his own birthday party. This comes as a big Mood Whiplash for people familiar with the Waluigi strips. As mentioned in the newspost, one forum member rewrote the Downer Ending of the strip to portray Waluigi as someone who prefers to celebrate alone and another wrote an alternate version where Luigi came by.
• In the achingly beautiful Counting Stars, the main character comes home on her 16th birthday to find a cupcake and a note of apology from her mother. She has no friends and no one with whom to share the special day, and is clearly despondent.
• Narrowly averted in the Birthday Episode of Cobweb and Stripes, when Lydia turns 19. Her apologetic father must be out of town for a business meeting, and her oblivious stepmother has a gallery showing of her hideous art. Fortunately for the birthday girl, Betelgeuse is eavesdropping on the conversation and arranges for a much better celebration.
• In The Handbook of Heroes comic "Throw Anything", Thief celebrates her birthday alone after discovering that her Throw Anything feat does not apply to throwing parties.
• In Happy Birthday to Me from Loading Artist.
• Played with in one The Owl House comic by MoringMark, where Eda actually has a large group of people band together to throw her a birthday party despite the fact that they're all trying to survive in a post-apocalyptic wasteland. Luz on the other hand is shown sitting in the dark with a cupcake on Earth, quietly wishing Eda a happy birthday while not even knowing if she's alive much less that she has others with her.

Not even Ghostbur, the one in charge of delivering the invitations, showed up. Later, this turns out to be invoked, Dream took the invitations from Ghostbur, sent him off to go for a walk in the snow (Ghostbur melts when he touches water, though he thankfully survived that ordeal), and played dumb when Tommy asked if anything happened to the invitations.
  Dream: I made sure nobody would show up to your party, so that you'd have no friends except me.
• In the LoadingReadyRun Crapshot "The Cooking", The Decadent Man (Ian Horner's eccentric upper-class aristocrat character) tells the viewer about the decadence of sous vide cooking. Cut to him pulling a fully-baked, iced cupcake out of his cooking rig, singing "Happy Birthday" to himself and digging in with a spoon.
• Neuro-sama: In keeping with Vedal's trend of Parental Favoritism, Evil Neuro's birthday stream was just herself. She even sang happy birthday to herself, and insisted her family was simply busy.
• StacheBros: In "Episode 2-4 — The Creature From The Egg" of "Mario & Luigi! Stache Bros", Waluigi is introduced alone at his birthday party. Depressed that no one seems to care about his birthday, Waluigi just sits and listens to his mood music...that is, until the boombox explodes.

Western Animation

• A good number of childhood flashbacks in Archer involve Sterling sitting by himself crying. One related to his birthday had him in a run-down apartment all by himself, his butler/nanny locked in a bathroom getting high and his mother out of the country on a secret agent job ("Guatemala's democratically-elected government wasn't gonna overthrow itself!"). Then Sterling's anonymous father entered to give him a stuffed alligator. Given the adult Sterling has an intense and uncharacteristic fear and hatred of alligators, it's not clear quite what that means on a psychological level.
• The Cow and Chicken episode "Factory Follies", in which Red Guy plays the foreman of a factory who treats his employees like worthless slaves. At the end of the workday, he reminds everyone that his surprise birthday party will be held in the conference room later that night. Of course, nobody shows up, so he throws the party for himself and sings, "Oh birthday boy, add one more year/oh birthday boy with a big fat rear!"

Cue to Coop recalling all the times Jamie has left him hanging, including Coop waiting alone in front of a movie theater, at the amusement park, this trope as Coop sits alone at a table for his birthday party, and then Coop sitting alone at a table for Jamie's birthday party.
• The My Little Pony: Friendship Is Magic episode "Party of One" plays with this one. Pinkie celebrates a party with a bunch of inanimate objects because her friends were busy, and she thinks that they don't want to be her friends anymore — but the party in question is for (the day after) her pet alligator's birthday, not her own. At the end, it's revealed that the real reason her friends can't attend this party is because they're organizing a surprise party for Pinkie's birthday. Pinkie had somehow completely forgotten her own birthday. Since she only attends this party after Rainbow Dash drags her there, the cast almost winds up with a party where everyone except the birthday girl shows up.
• Exaggerated and parodied in the backstory of Doofenshmirtz in Phineas and Ferb. He states that neither of his parents bothered to show up to his birth, and that he had to throw surprise birthday parties for himself. Also, at age eight, he was abandoned at a Suck E. Cheese's to the point that the employees working there let him lock up the shop at closing.
• The Simpsons:
  • In "The Haw-Hawed Couple", Nelson throws a birthday party and invites all of his classmates. Bart is the only one to turn up because Marge forces him to go.

    Happy birthday to me.
